Hi! 
I'm stumped. I have somewhere around 12 hens.... I think (lost too many to count)
Yesterday I noticed an EE, who is in heavy molt, looked skinny from afar. When I checked her out she had very poor body condition. I could sharply feel her keel and her ribs. Her crop was empty.
I separated her for a day with food and water.
I have an elderly hen who is very obese. She gets around slow.
Checks on the other hens which revealed 2 mildly obese hens, and most well fed.
The other EE, with an unexplained limp, is also skinny.
All 3 Leghorns are either obese or on the high end of well fed. My JG are in good body condition, my incessant fake broody is just fine.
The separated EE didn't eat anything at all and barely drank. But put back outside she devoured grass.
So in total
3 obese (2 Leghorns)
Most well fed
2 starving (EE)
I am feeding Naturwise 18% layer as of 4 days ago. Previously fed 16% Naturewise layer.
All free range every day.
I have a 5gal feeder always with feed and 2 small dishes that also hold feed to reduce competition.
Am I doing something wrong? Is there bullying? What could be going on?
TIA,
Cyprus
P.S only the one EE is molting.
